at my school if your paper didn't answer the question you received 0%, I realise schools these days believe everyone deserves a medal, any indication of failure having dire consequences on ego. As for deleting the thread, one poster is hijacking it with superfluous information that can be found on
Blackbird's thrust questionand not addressing the OP. Waste of bandwidth.
There are a few places on PPRUNE including this one where it's hard to waste bandwidth even with a deviated technical direction in some eyes. Did you ever notice that very few threads get closed here? They just continue as long as there is readership and no playing the man instead of the ball.
If the OP were to judged on-topic responses then I suspect that there is an agenda rather than a question of learning something of benefit for the rest of us.
